The Growing Threat of Catastrophic Storm Surge in the Next 30 Years on a Fast, Global Warming Induced, Sea Level Rise and its Consequences for Coastal Cities and Humanity

By Malcolm P.R. LightNovember 11, 2012

Abstract

Methane is erupting as widespread torches and fountains in the Arctic ocean up to 1 km across and is exponentially increasing in concentration in the Arctic atmosphere (Shakova et al. 2008 and 2010; Light and Carana 2012; Light 2012). The Arctic atmospheric methane is mostly derived from Arctic subsea shelf and slope methane hydrates due to their destabilization by globally warmed Gulf Stream currents which enter the Arctic west of Svalbard and through the Barents Sea. In the North Atlantic, the surface of the Gulf Stream is heated in the summer and is marked by excessive evaporation due to the global warming effects of pollution clouds emanating from North America (Figure 5; IPCC Working Group 1. Fig. 10.12 Lavatus Prodeo, 2012).

The exponential increase in Arctic atmospheric methane has caused an exponential decrease in the volume of Arctic sea ice and in the continent wide reflectivity (albedo) of the Greenland ice cap (Light 2012; NASA Mod 10A1 data, from Carana, 2012). The atmospheric Arctic methane which is almost half the density of air is rising like hydrogen into the Stratosphere where it is forming and all encompassing global warming veil further aggravating the global warming of the lower level greenhouse gas clouds.

The ice melt back curves from the oldest lower 5* year old ice to the youngest shallowest 2 and 1 year old ice are caused by the progressive increase in temperature of the Gulf Stream “Atlantic Waters” which are entering the Arctic beneath the ice and melting it from the bottom up. The heating of the Gulf Stream waters is directly linked to the global warming of the North Atlantic caused by green house gas pollution blowing east off North America.

Above summary diagram (Figure 15, click on image to enlarge) shows all the determined global warming temperature curves and the latest "Sandy" storm surge curve based on a mean storm surge of 14 feet added to the mean latent heat of ice melting curve (Light 2012; Fichetti, 2012). All the global warming curves converge on a region between 2034 and 2052 where the mean atmospheric temperature anomaly will be greater than 8°C and all of the Earth's ice caps will have melted with a consequent sea level rise of 68.3 m (224 feet) above mean sea level (Wales, 2012). In particular the accelerated global warming curve from Carana (2012) and the "Sandy" storm surge curve converge on the mean atmospheric temperature extinction point derived from 20 estimates (Light 2012). This gives great confidence in the interpretation that we can expect catastrophic climate change from methane induced global warming between 2034 and 2052 unless humanity sharply cuts back some 90 to 95% on global greenhouse gas emissions and converts all its energy resources to renewable energy/ nuclear power.

A series of progressive extinction zones have been determined (after Parry et al. 2007) and include:-

Bleaching of most corals when the atmospheric temperature anomaly is between 1 and 2°C

Extreme droughts will extend over 1 - 30% of the land area when the atmospheric temperature anomaly exceeds 2°C which will make more than 1.8 billion people water stressed.

Widespread coral mortality will occur when the mean atmospheric temperature anomaly is between 2.5°C and 3.5°C and will be associated with a massive increase in the ferocity of tropical cyclones/hurricanes far in excess of the Sandy super storm.

Complete deglaciation and coastal inundation is expected when the mean atmospheric temperature anomaly increases from 4 to 8°C with a consequent sea level rise of some 68.3 metres (224 feet) above sea level. There will be major global extinction over this temperature interval as cereal production sharply decreases outside of the tropics.

Super storm Sandy has shown that Manhattan is already open to storm surge flooding and by 2016 when the Arctic Ocean begins to be free of ice, we can expect more violent hurricanes bearing down on the eastern coastline of the United States and increasing catastrophic damage to the coastal cities there.

The Alamo Project is a call for United States scientists and engineers to volunteer to develop a system of destroying the fast growing methane clouds in the atmosphere by radio/laser means or other processes before they destroy us. See this page:-http://www.facebook.com/AlamoProject

Immediate and concerted action must be taken by governments and oil companies to depressurize the Arctic subsea methane reserves by extracting the methane, liquefying it and selling it as a green house gas energy source (see the ANGELS Project). See this post:-http://arctic-news.blogspot.com/2012/06/angels-proposal.html

If greenhouse gas emissions are not sharply curtailed by 90% to 95% and the Arctic subsea and atmospheric methane extracted and destroyed, mean rising sea levels will breach the Thames Barrier by 2029 flooding London and the proposed Verrazano Narrows barrier in New York by 2030. The base of the Washington Monument (D.C.) will be inundated by 2031. By 2051, total global deglaciation will finally cause the sea level to rise up the lower 35% of the Washington Monument and humanity will have been eliminated by worldwide flooding and firestorms.

Introduction

Satellite atmospheric methane concentration data over the Arctic region between November 2008 and November 2011 indicate a rapid build up of methane around 7 km altitude (Figure 1; Yurganov 2012 in Carana 2012) and by 2012 the low level methane clouds have continued to thicken and spread pervasively into Russia, Europe, Alaska, Canada and Greenland (Figure 2; Yurganov 2012).

This methane has almost half the density the cold dry polar air at STP (Engineering Toolbox, 2011) and rises like hydrogen into the stratosphere where it is accumulating as a world encompassing methane warming veil (methane in wet air may be transported horizontally by storm systems (Light, 2012).). In addition because methane has a global warming potential of close to 100 during the first 15 to 20 years of its life (Dessus et al. 2001) it will preferentially warm up and expand compared to the other atmospheric gases and thus drop even further in density making it much lighter than the cold polar air. This means that 1 ppmv of methane (1000 ppb methane) is equivalent to 100 ppmv carbon dioxide making its global warming effect far exceed that of carbon dioxide.

The rising light Arctic methane migration routes have been interpreted on a Hippo profile (from Wofsy et al. et al. 2009) using the inflexion points on the temperature and methane concentration profiles similar to the system used to identify deep oceanic current trends using salinity and temperature data (Tharp and Frankel, 1986). The light Arctic methane is rising almost vertically up into the stratosphere between 60° North and the North Pole where it is trapped below the hydrogen in the upper stratosphere against which it has an upper diffuse boundary as shown by the fall off in methane concentration between 40 km and 50 km altitude (Nassar et al. 2005). A further very important consequence of the light methane rising like hydrogen into the upper stratosphere where it forms a stable zone beneath the hydrogen between 30 km and 50 km height, is that this methane is never recorded in the mean global warming gas measurements made at Mauna Loa.

The Arctic atmospheric methane is being generated by the destabilization of subsea Arctic Ocean shelf and slope methane hydrates (Figure 3, Max and Lowrie 1993). If only a few percent of these methane hydrates become destabilized they will release enough methane into the atmosphere to cause total extinction of all life on the surface of the Earth from the resulting global warming induced heat wave and firestorm (Light 2011, 2012; Light and Solana, 2002).

Some of the methane hydrate is associated with the spreading Gakkel Ridge hydrothermal activity and is being destabilized by earthquakes as indicated by high concentrations of major faults in the zones of maximum subsea eruptions (Figure 4a; Harrison et al. 2008). The zone of extreme methane emission shown on Figure 4a is represented by the anomalously high methane concentration peaks some exceeding 8 ppmv in the Laptev Sea and East Siberia Sea on Figure 4b (from Pravettoni, 2009) and show that subsea atmospheric methane emissions were already climbing here before 2005.

However the main methane hydrate destabilizing factor is the Arctic extension of the globally warmed Gulf Stream which splits and enters the Arctic region flowing beneath the drift ice west of Svalbard and through the Barents Sea. These two hot Gulf Stream currents converge on the slope region of the East Siberian Shelf (Coachman and Barnes, 1963; MIT 2012; Wales 2012; Shakova et al, 2008; 2010) causing widespread destabilization of the subsea methane hydrates and Arctic methane eruption into the atmosphere. This warm Gulf Stream water is now progressively destabilizing more and more of the methane hydrates releasing increasing amounts of methane into the already globally warmed Arctic atmosphere heating it further.

The Gulf Stream which starts SW of Florida, crosses and bifurcates in the Atlantic where it undergoes excessive global warming in Summer and forms an area of extreme evaporation (Figure 6; Light 2012; Shakova et al. 2008, 2010; Devconsultancy 2010). A southern cyclic branch of the Gulf stream develops Hurricanes off West Africa and leads them back to the Caribbean and the East Coast of the United States and Canada as has just been exemplified by the devastating super storm Sandy (Figure 6). The north east branch of the Gulf Stream (North Atlantic Circulation) warms Western Europe and the increasing Gulf Stream evaporation is causing a large increase in European rainfall, This NE branch of the Gulf Stream enters the Arctic Ocean west of Svalbard with a separate branch via the Barents Sea and where these two branches converge on the shelf slope region at the end of the Eurasian Basin in the Laptev Sea they destabilize the methane hydrates (see Figures 4a, 4b and 6) producing an exponential increase in the rate at which subsea methane is erupting into the Arctic atmosphere as fountains (torches) up to 1 km across (Figures 6; Light 2012; Shakova et al. 2008; 2010).

The recent super storm Sandy (Figure 7) in late October 2012 linked with an Arctic cold front and generated a massive tidal surge at New York in excess of 14 feet above mean sea level causing widespread deaths, devastation, fires and electric power black outs for millions of Americans. Super storm Sandy was formed by the convergence of Gulf Stream (atmospheric methane emission) globally heated Arctic air and a Gulf Stream generated tropical super storm - hurricane (Figure 7; Eoimages, 2012). NASA modelling shows that the methane being emitted in the Arctic is rising up into the stratosphere where it forms a continuous Methane Stratospheric Global Warming Veil. The methane concentration is at present densest in the equatorial and mid -latitudes where reaches concentrations of 1.8 ppmv, much higher than occurs at lower levels in the atmosphere and this stratospheric methane is progressively spreading northwards over the region where super storm Sandy ran aground onto the eastern coastline of the United States (Figure 8; NASA, 2012). The continuous Methane Stratospheric Global Warming Veil is causing extreme heating of the Earth's surface by trapping the suns heat below it and is further increasing the amount of heating and evaporation that is taking place over the Central Atlantic (Figure 8).

Data Sources

The massive 14 foot tidal surge (Scientific American 2012). caused by the Sandy super storm has been combined with the complete set of Arctic atmospheric global warming sea ice melt back and sea level rise data to produce a complete analysis of the likely trend of the global warming induced extinction events in the next 50 years.

The sharp increase in methane emissions at Svalbard north of Norway indicate that by the end of August 2010 the concentration of atmospheric methane sourced from the destabilization of subsea methane hydrates was growing at an increased and anomalous rate as was confirmed later by data from Barrow Point Alaska (Figure 9; NOAA 2011a; Carana 2012).

In addition data from Piomass volume of Arctic melt back show that the Arctic Sea ice has shrunk at a much faster rate than predicted by IPCC modelling projections (Figure 10; Stroeve 2007; NSIDC, Naam 2012), enabling a date correction to be applied to the mean IPCC global atmospheric trend for the Arctic region (Light 2012).

Figure 11 shows an exponential regression of the Piomas yearly minimum ice volume data indicating that the start of complete melt back Arctic sea ice will begin in 2015 and it also gives the range of the exponential estimate (Zhang and Rothrock 2003; Wipneus 2012).

The exponential regression of some of the twelve Piomas monthly average Arctic ice volumes are shown on Figure 12 and have been used to determine monthly melt back times (Zhang and Rothrock, 2003; Wipneus 2012).

Giss maximum surface mean monthly maximum temperature anomalies (NASA 2012) have been used to generate 12 converging amplitude envelopes of the 11 year moving average with the final mean convergent point fixed at 2015.757 which is almost identical to the Piomas estimates of the start of Arctic sea ice melt back (Figure 14).

This point represents the mean start point of complete Arctic sea ice melt back because the convergence in the amplitude of the monthly Giss surface temperature anomalies is caused by the latent heat of melting and freezing of the surface Arctic ice which is progressively diminishing until it is finally gone by about 2015.757.

Figure 15 (clickon image to enlarge) is a summary diagram showing all the determined global warming temperature curves and the latest "Sandy" storm surge curve based on adding 14 feet to the mean latent heat of ice melting curve (Light 2012; Fichetti, 2012). All the global warming curves converge on a region between 2034 and 2052 where the atmospheric temperature anomaly will be greater than 8°C and all of the Earth's ice caps will have melted with a consequent sea level rise of 68.3 metres (224 feet) above mean sea level (Wales, 2012). In particular the accelerated global warming curve from Carana (2012) and the "Sandy" storm surge curve (data from Fichetti, 2012) converge on the mean atmospheric temperature extinction point derived from 20 estimates (Light 2012). This gives great confidence in the interpretation that we can expect catastrophic climate change from methane induced global warming between 2034 and 2052 unless humanity sharply cuts back (90 - 95 %) on global greenhouse gas emissions and converts all its energy resources to renewable energy/ nuclear power.

Figure 16 (click on image to enlarge) shows all the progressive extinction events caused by the rising atmospheric temperature due to global warming based on IPCC data (Parry et al. 2007). All the determined global warming temperature curves converge on a region between 2034 and 2052 where the mean atmospheric temperature anomaly will be greater then 8°C and all the worlds ice caps will have completely melted. The progressive extinction zones shown on this diagram from Parry et al. 2007 and include:-

Bleaching of most corals when the atmospheric temperature anomaly is between 1 and 2°C

Extreme droughts will extend over 1 - 30% of the land area when the atmospheric temperature anomaly exceeds 2°C which will make more than 1.8 billion people water stressed.

Widespread coral mortality will occur when the mean atmospheric temperature anomaly is between 2.5°C and 3.5°C which will be associated with a massive increase in the ferocity of tropical cyclones/hurricanes far in excess of the Sandy super storm (Fichetti 2012).

Complete deglaciation and coastal inundation will occur when the mean atmospheric temperature anomaly increases from 4 to 8 degrees C with a consequent sea level rise of some 68.3 metres (224 feet) above sea level. Major global extinction will occur over this temperature interval as cereal production sharply decreases outside of the tropics.

Arctic Sea Ice Melt Back Times

Arctic sea ice melt back times have been estimated from the area, volume and thickness of the Arctic sea ice and include Piomas yearly average Arctic sea volumes (Zhang and Rothrock, 2003, 2012), NSIDC yearly average Arctic ice areas (Tschudi and Maslanik, 2012) and mean Arctic shelf ice thickness (Kwok and Rothrock, 2008)(Figure 17; Table 1).

Giss convergence trends on mean maximum monthly surface temperature data (NASA, Hansen 2012) are also shown and correlate very well with the Piomass Arctic sea ice volume melt back time of 2016 (Figure 17, Table 1). The mean Arctic sea ice total melt back time from 41 estimates is between 2022 and 2023 and the ice will be entirely gone between 2037 and 2040 (Figure 17, Table 1).

The upper part of Figure 17 is a composite of Piomas Arctic sea ice volume start and end exponential regression trends, a graph of the decreasing mean thickness of Arctic sea ice in metres (from Kwok and Rothrock, 2008) and a atmospheric temperature graph showing the various extinction zones from Parry et al. 2007.

The lower part of Figure 17 defines the NSIDC area sea ice extent in millions of square kilometres and shows the progressive melt back of the 5+ year old, 4 year old, 3 year old and 2 year old sea ice by 2037. The ice melt back from the oldest lower 5* year old ice to the youngest shallowest 2 and 1 year old ice is caused by the progressive increase in temperature of the Gulf Stream “Atlantic Waters” which are entering the Arctic beneath the ice and melting it from the bottom up. The heating of the Gulf Stream waters is directly linked to the global warming of the North Atlantic caused by green house gas pollution blowing east off North America.

It also graphically shows the progressive opening and expansion of the dark (low albedo) Arctic ocean and the trend of the globally warmed Gulf Stream/Atlantic waters along the European - Russian shelf edge - slope where it is destabilizing the methane hydrates and releasing vast quantities of methane into the Arctic atmosphere before its cyclic return to the North Atlantic in the Arctic drift ice region.

Table 1 shows the Arctic sea ice melt back data from Piomass ice volume (Zang and Rothrock 2003, 2012), area (NSIDC , Tschudi and Maslanik 2012) and Giss surface maximum convergence data (NASA, Hansen 2012). Major Arctic methane emissions were observed at Svalbard at the end of August 2010 (Figure 9) but Pravettoni (2009) indicate that anomalous methane emissions into the Arctic atmosphere began before that time and had exceeded 8 ppmv and 6 ppmv in the area of the Laptev and East Siberia Seas before 2005 (Figure 4b) This methane concentration is equivalent to 600 to 800 ppmv of additional carbon dioxide added to the atmosphere at a methane global warming potential of 100 (Dessus et al. 2008). This shows that even before 2009, the atmospheric methane content in the Laptev sea had in places exceeded twice the global warming effect of the present mean global atmospheric concentration of carbon dioxide generating a relative temperature anomaly of more than 8°C.

The exponential increase in the rate of Arctic methane emissions will cause a continuous zone in the Arctic clear of sea ice after 2016 (Table 1). This low albedo open Arctic ocean will have no ice cover at all and will absorb large quantities of solar energy quickly heating the water up, further destabilizing the subsea shelf and slope methane hydrates and releasing large quantities of methane into the Arctic atmosphere and stratosphere where it will thicken and extend as an all encompassing global warming veil further aggravating the already serious global warming of the Earth's surface.

The oldest, 5+ year old Arctic sea ice will be completely melted by 2022 followed immediately by the 4 year old ice in 2023 and these times also represent the mean time for the complete melt back of all of the Arctic sea ice (Table 1). The 3 year old ice is expected to be completely melted by 2026 and the 2 year old ice completely gone by 2037 (Table 1). The 2037 melt back date for the 2 year old ice also corresponds with final date of the total melt back of all the Arctic sea ice (Piomas maximum ice volume exponential regression trend) while a linear extrapolation of the decline of Arctic sea ice mean thickness reaches zero around 2040 (data from Kwok and Rothrock, 2009). This implies that there will be complete melting and loss of the entire 2 year old and 1 year old Arctic ice by 2037 to 2040 (Table 1). The low albedo Arctic Ocean will now have no ice cover at all and will absorb large quantities of solar energy causing massive warming of the ocean waters and extreme destabilization of the subsea methane hydrates releasing large volumes of methane directly into the Arctic atmosphere. Exponential trends on the 1 year sea ice area data suggest that snow will finally cease to fall in the Arctic region between 2066 and 2067.

Sea Level Rise

Global and Arctic Atmosphere and ice melt back temperature curves which show the rate of sea level rise and the time of flooding of world oceanic islands and coastal cities are shown on Figures 18 to 27 and Tables 1 and 2. These diagrams have a mean latent heat of ice cap melting curve for which the sea level rise has been calculated from 2015 and this reaches a maximum of 68.3 meters (224 feet) by 2051. In addition the minimum and maximum latent heat of ice melting curves have also been estimated from the range shown by the exponential regression trends on the Piomass ice volume curve in Figure 11.

A yellow global extinction zone is outlined vertically on the diagrams between an atmospheric temperature anomaly of 2°C and 8°C and the Giss surface maximum temperature curve defined from the monthly convergence data (Light, 2012). The yellow global extinction zone is bounded laterally by the maximum and minimum latent heat of Arctic ice melting curves.

A "Sandy" storm surge of 14 feet above sea level has been added to the mean Arctic sea level rise calculated from the mean latent heat of ice melting curve and used to calculate a "Sandy" storm surge curve. The relative altitude and time of flooding of particular islands and cities are shown by horizontal blue lines in Figures 18 to 27. The intersection of these blue lines with the mean latent heat of ice melting curve gives the mean time of flooding from sea level rise/sea barrier breaching under fair weather conditions. The intersection of the island/city altitude blue lines with the "Sandy" storm surge curve gives the time of flooding under extreme to catastrophic tropical storm/cyclone/hurricane conditions. Because the storm systems are going to increase in intensity as global warming accelerates, the estimated flooding time is a maximum future time and the flooding could occur even earlier depending on the ferocity of the storms.

The following list shows the regions dealt with in the diagrams 18 to 27 which graphically display the data in Table 2.

The maximum time of inundation of various coastal cities, coastlines and coastal barriers is also shown on Table 2 (after Hillen et al. 2010; Hargraves, 2012).

Rising sea levels will breach the Thames Barrier by 2029 flooding London and the proposed Verrazano Narrows barrier in New York by 2030.

The base of the Washington Monument (D.C.) will be inundated by 2031. Total global deglaciation will cause the sea level to rise up the lower 35% of the Washington Monument by 2051 (68.3 m or 224 feet above present sea level).

Because of the massive increase in the strength of the storm systems and waves, high rise buildings in many of the coastal city centers will suffer irreparable damage and collapse so that the core zones of the cities will be represented by a massive pile of wave pulverised debris. Unfortunately by that time a large portion of sea life will be extinct and the city debris fields will not form a haven for coral reefs.

The seas will probably still be occupied by the long lasting giant jellyfish (such as are now fished off Japan), rays and sharks (living respectively since 670, 415 and 380 million years ago) and the sea floor by coeolocanths (living since 400 million years ago)(Calder, 1984).

The city rubble zones will probably be occupied by predatory fish (living since 425 million years ago)(Calder 1984). Life will also continue in the vicinity of oceanic black smokers so long as the oceans remain below boiling point.

Alamo Project

When the Arctic ice cap melts towards the end of 2015, there will be a massive increase in the amount of heat being absorbed by the Arctic ocean from the sun and the Gulf Stream which presently feeds the Arctic with Atlantic water along the west side of Svalbard and through the Barents Sea. Normally, the Gulf Stream is cooled when it hits the floating ice pack and this will cease to happen bringing even vaster amounts of Atlantic heat via the Gulf Stream into the Arctic. Consequently, the Arctic subsea methane hydrates will destabilize at an even faster rate, because of the increasing Arctic Ocean temperature, pouring methane into the Arctic atmosphere and stratosphere.

The extreme weather events in the United States this year which included record heating and drought conditions, massive loss of food crops with farmers going bankrupt, more hurricane flooding in New Orleans and tornadoes and the Super storm Sandy in New York are just a small sample of what will come in the next four or five summers as the Arctic ice finally melts. The Arctic ice cap works like the Earth's air conditioner because of the latent heat of melting and freezing of the floating ice and its moderating effect on atmospheric temperatures.

The extensive stratospheric methane warming veil that is spreading over the United States is undoubtedly the reason for the extreme weather events and very high temperatures. The livelihoods of all the American people are going to be totally compromised in the next few years, unless we develop a system of destroying the atmospheric methane that is erupting in the Arctic from the destabilization of submarine methane hydrates and the methane that is accumulating as a global warming veil in the stratosphere.

We need to act.

We are facing impossible odds with regard to the Arctic ocean methane release and in the same way that Colonel Travis drew a line at the Alamo to ask for volunteers to help him defend the mission against Santa Ana's massive Mexican army, I am drawing a virtual line through the snow on the top of the Arctic ice pack to ask for volunteers to defend the American people from the fast-gathering Arctic methane global firestorm.

We desperately need dedicated scientists and engineers to volunteer to develop an effective 'action at a distance' method of destroying the Arctic oceanic methane clouds as they are erupting from the sea surface and entering the stratosphere and mesosphere. This could be done using a 13.56 MHz methane destruction radio frequency which has been used in the laboratory to convert methane to nano diamonds, methane molecule vibrational frequency lasers or other geoengineering methods. If the United States can land giant rovers on the mars with a skycrane, surely American engineers and scientists are up to this challenge. We need to get rid of as much of this atmospheric methane as we can, to drop the polar temperatures to reasonable levels. This will of course have to go hand in hand with a massive cut back in carbon dioxide emissions from all developed and developing countries.

If left alone the subsea Arctic methane hydrates will explosively destabilize on their own due to global warming and produce a massive Arctic wide methane “blowout” that will lead to humanity’s total extinction, probably before the middle of this century (Light 2012 a, b and c). AIRS atmospheric methane concentration data between 2008 and 2012 (Yurganov 2012) show that the Arctic has already entered the early stages of a subsea methane “blowout” so we need to step in as soon as we can (e.g. 2015) to prevent it escalating any further (Light 2012c).

After the Arctic sea ice has gone (probably around 2015) we propose that a large consortium of oil and gas companies/governments set up drilling platforms near the regions of maximum subsea methane emissions and drill a whole series of shallow directional production drill holes into the subsea sub permafrost “free methane” reservoir in order to depressurize it in a controlled manner (Light 2012c). This methane will be produced to the surface, liquefied, stored and transported on LNG tankers as a “green energy” source to all nations, totally replacing oil and coal as the major energy source (Light 2012c). The subsea methane reserves are so large that they can supply the entire earth’s energy needs for several hundreds of years (Light 2012c). By sufficiently depressurizing the Arctic subsea sub permafrost methane it will be possible to draw down Arctic ocean water through the old eruption sites and fracture systems and destabilize the methane hydrates in a controlled way thus shutting down the entire Arctic subsea methane blowout (Light 2012c).

Many thanks to Harold Hensel for finding additional data on the extreme methane emission points in the Arctic which confirmed the mapping procedures used in previous analyses of the Arctic region. My grateful thanks also go to Sam Carana for his stirling editing work on my many global warming articles in the Arctic News.

Here is comment I posted on Google+ about public perception, they won't mind cross post I'm pretty sure.

"Some may be put off by the conclusion sea level will rise most likely 224ft or 68.3m by 2051 and conclude to dismiss convergent analysis.But to the layman and others who don't pay attention -acceleration;Logarithmic progression of cascade of complicating factors applies.﻿"

Here are notes made this morning before I went to write stuff on line, to try to focus.. Test: pen works - Earth + humanity are in testthe test of time and importanceNow in any good test of CollegeToo much info/spurious infoone missing item/multiple variables--------Water is key latent heat + capacityVol time/buffer effectVariability of outside factors-------Need Allies Need PeaceEvery Word in order too.

end quote but had to look up spelling of spurious and variability..The point I'm trying to make is every word we use today is needed..Directed in a way to have peace and calm and so full force - applies to what we do now in an effort to head off Runway global warming from going full on..Abrupt Climate Change is happening now, this above accelerated global warmingThe slide to point where sudden volley of CH4 release is likely complete and yet even now as COP18 Doha takes place the world is tone deaf to situation..Yet we leave use of fossil carbon on an acceleration even as we are agent of our own destruction and that of Earth's life system which made weak Heaven..

Global temperatures are rising fast. In the Arctic, temperatures are rising even faster (interactive charts below and right). For 2010 and 2011, NASA recorded anomalies of over 2°C at higher latitudes (64N to 90N), with anomalies of over 3°C at latitudes 79N and 81N in 2010.

For November 2010, anomalies of 12.5°C were recorded at latitude 71N, longitude -79 (Baffin Island, Canada). At specific moments in time and at specific locations, anomalies can be even more striking. As an example, on January 6, 2011, temperature in Coral Harbour, located at the northwest corner of Hudson Bay in the province of Nunavut, Canada, was 30°C (54°F) above average.
